Backpressure in document pipelines is an architecture problem, not only an ops problem

When document teams talk about reliability, they often focus on extraction quality first. That makes sense, but another issue shows up quickly in real workflows: backpressure. Documents arrive in bursts, review queues expand unevenly, retries accumulate, and the system starts feeling unreliable long before it visibly breaks. This is not just an operations issue. It is an architecture issue. What broke Backpressure usually appears through workflow symptoms: Clean cases and unclear cases compete for the same path. Retries consume capacity that should be reserved for forward progress. Reviewers receive cases without enough context, which slows triage. Urgent documents get buried inside generic backlog handling. Monitoring focuses on service health but not queue composition. At that point, the workflow may still be “up,” but the design is already leaking friction. A practical approach A more resilient document architecture separates concerns explicitly. I would usually want: A clean path f
